Spherical Mobile Military Robot

The NY Times has an article
on a new military robot proposed by Ranjan Mukherjee of
Michigan State University. Mukherjee has just received a patent for a
spherical mobile robot design that he has been researching for several
years. When in motion, the robot is a
featureless metal ball. When it comes to rest, it stablizes itself on
three legs and extends sensor and weapon arrays.
